Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed November '7, 1904. Serial No. 281,713.

l 1 l l zen of the United States, and a resident of the 1 city of New York, borough of Manhattan, in l the county and State of New York, have invented a new and Improved Bung, of which the following is a full, clear, and exact description.

Myinvention relates to bungs, and although it is capable of uses for all purposes to which bungs are applied it is especially adapted for use upon beer and ale barrels and the like.

The principal objects of the invention are to provide means whereby the tube of a fancet can be introduced through the bung into the barrel without danger of any of the contents being discharged except through the faucet.

Further objects of the invention are to provide means for closing the passage through which the tube is admitted, for locking the valve in closed position, and for unlocking it when the parts are in such position as to permit the tube to be thrust through the bung.

Additional objects of the invention, largely dependent upon and related with those mentioned above, will appear in the course of the subjoined description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a central sectional view on the line 1 1 of Fig. 2, showinga practical embodiment of my invention. Fig. 2 is an elevation of the same, taken from the inside. Fig. 3 is an elevation taken from the outside. Fig. -.t

is a sectional view of the wall of the receptacle, showing the parts of the bung in elevation. Fig. 5 is a sectional view similar to Fig. 1, but showing the parts in another position. Fig. 6 is a central sectional view on the line 6 6 of Fig. '7, showing another embodiment of my invention. Fig. T is an elevation of the same, taken from the inside of thereceptacle. Fig. Sis a sectional view similar to Fig. 6, showing the parts in another position; and Fig. 9 is a fragmentary sectional view on an enlarged scale on the line 9 9 of Fig. 6.

Referring to the first five figures, a represents the wall of the receptacle, and Z) the main portion of the bung, which is threaded or secured in an opening of the wall of the receptacle in any convenient or desired manner. The bung is hollow and is provided with a cap 0, which in this embodiment of the invention is secured between projections 7/ and a collar (,1, which is screwed to the internal wall of the bung. A packing a is provided between the collar (7 and the bung. Although secured in its position with respect to the bung, the cap 0 is capable of turning upon its own axis. It is provided with project-ions 0, between which is pivoted a flap-valve f. It will be readily understood that any other kind of a valve may be employed and that the necessary modifications in the parts to operate it which would have to be made come within the scope of my invention. This valve is provided with a packingf", seating upon the inner edge of a perforation c, with which the cap a is provided. The valve is also provided with a rear extension f, which is adapted to ride upon an inclined surface 71 upon the bung 7). For the purpose of turning the cap 0 a key 5/ is provided. This key has a projection 5 extending into a depression a in the cap. This projection lits the depression and is provided with lugs by means of which it will be obvious that the turning of the key will turn the cap. A perforation is provided in the key, registering with the perforation o in the cap. The bung is also provided with a track 71 with which lugs 1" on the key engage and which is designed to guide the key and force it toward the cap when the key is inserted in the bung and turned. These lugs 7" are adapted to enter recesses 7) between the tracks 7). The parts are so related to each other that when the key is placed with the lugs 7" in the recesses 7)" the projection f will be at the highest point of the incline .7)", and consequently the valvef' will be securely locked in closed position. .It will therefore be seen that when the key is removed the valve is locked and no liquid can pass through the bung. Upon inserting the key it is turned by means of a projection so that the lugs g" ride up the tracks 0. This forces the key toward the cap and compresses a packing 7!. between them, thus providing an additional safeguard against the passage of liquid.

The faucet, which may be of any ordinary or desired construction and is not illustrated,

, is placed with its tube in the passages g and r, and when the key is turned far enough to permit the projection f to ride down the incline if to the end thereof the valve f may may be forced open by the tube of the faucet, so as to permit liquid to enter the tube and the passages in the cap and key. The faucet may be secured to the key in any desired manner, so as to prevent the passage of liquid between the key and faucet. When it is desired to remove the faucet, the tube is drawn into the passages g and c and the key is turned into such a position that the lugs g* can pass out through the spaces 5*, and in this position the projection f will ride up upon the incline Z9 again, so that the valve will be forced to a closed position and locked there. If it is desired to remove the cap when the receptacle is empty, the key is turned around to a position at one hundred and eighty degrees from that in which the valve is closed, as shown in Fig. 1. This position permits the key to be withdrawn, as it places each lug 9* in the opposite passage Zf from that in which it was placed when the key was inserted in the bung. It also allows the valve f to be open, as shown in Fig. 5, for the reason that the projection f is entirely away from the inclined surface 5 It also permits the cap to be removed for the reason that a passage 6 is provided in the projection Z),preferablyoppositetothehighest point of the surface Z2 The collar (Z can be removed and then the cap 0 can be readily taken out, the projecting-portion of the valve f passing through the passage 6 Referring now to Figs. 6, 7, 8, and 9, the letters e, f, f, f. a, at .0 and it represent elements similar in construction to those represented by the same letters in the other figures; but in this case the cap here represented by the letter C is not rotatable in operation, but is screwed into fixed position with respect to the bung b. This cap is provided with a passage C for the same purpose as the passage 0 in the other form, but located at one side of the center instead of concentrically with the cap, as is the case in the other form. Instead of being pivoted at a point near the edge of the cap the valve 'f is pivoted at a point near the center on the projections 0, as in the other form. A second passage 0 is provided in the cap for the reception of a turning element D. This element is provided with an inclined surface D and with a projection D having flat sides D with which a projection G, having a depression G of the same shape as the projection D is adapted to engage. A packing E is provided between a shoulder D on the turning element and a fastening-ring D The inclined surface D is adapted to engage with the projection f on the valve and to close it and lock it in closed position in a manner similar to that described above. It will be readily understood that the turning of the key Q will cause the turning of the member D and the consequent manipulation of the valve f in the same manner as before. A further description of the operation of this modification is therefore believed to be unnecessary. When it is desired to remove the cap C, the key is first removed, and then the cap can be unscrewed in an obvious manner, taking with it the turning member D.

While I have illustrated and described only two forms of my invention, it will be readily understood that the same may be constructed in many other forms and that modifications of various kinds can be made in the forms herein shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
